Thanks for reply :)

I belive Rush consist of 3 independet parts: FS abstraction, OS
abstraction, drivers (local + remote over http).
So, I created similar components: Virtual File System (vfs), Virtual
Operating System (vos),
a couple of drivers (local + remote over ssh).
You can use them as independent components or as a whole and get thus
a Rush/Capistrano clone.

Actually I tried, but then decided that I like Rush API very much and
want it not only for my administration scripts but also for
my day-to-day programming, as a replacement of File/Dir/FileUtils, so
I created Vfs. It's very tiny, and doesn't have performance
loss compared to File/Dir/FileUtils (at least I belive in it :) ).
But if you also want extra stuff - just couple it with Vos and you'll
get it.

- yes they are pure ruby, local and ssh drivers also pure ruby.
- no, Vfs is FS-stuff only, it should be very small and simple,
nothing more. But you can use it with Vos (during the time there
should be all
features but right now there are only core features implemented).
- I hope it will be written in next week (because there will be some
minor issues and some refactoring needed), right now only the bare
code:
http://github.com/alexeypetrushin/my_cluster/blob/master/Rakefile
http://github.com/alexeypetrushin/my_cluster/blob/master/lib/services...
- I don't know Fabric, and yes as far as I know Capistrano it should
be able replace all features, not only basic (it's my guess,
I used Capistrano but don't examined it in deep details).
- I use it for management of my server, here are actual scripts
http://github.com/alexeypetrushin/my_cluster, I
guess it is usable but there may be bugs, and probably some of API
will change a little over time.
- there are 2 different goals Vfs should be File System Abstraction,
you should be able to use it over any FS-like storage (Local, Amazon
S3,
Hadoop, Remote-SSH, In-Memory, ...), Vfs+Vos+ClusterManagement should
became Administration Tools (not only deployment automation)
that allow you to do things your way (not the rails way only as it's
with capistrano).
- there should be possible to create and discuss issues on the
project's github page, later I'll add docs as github wikipages or as
standalone site.
Thanks for interest :).
